HEEL-BUILDING MACHINE.

Specification of Letters Patent.

Patented June 5, 1917.

Application filed March 25, 1916. Serial No. 86,614.

To all whom it may concern:

Be it known that we, JOHN E. MrronnLL and DnNNis PARKS, citizens of the United States, residing in the city of St. Louis and State of Missouri, have invented new and useful Improvements in Heel-Building Machines, of which the following is a specification.

This invention relates to heel-building machines, wherein a number of lifts necessary for forming a. heel-blank are succes sively delivered within easy reach of the operator and are then supplied with paste and assembled in a heel-former and afterward placed in a suitable holder. The said machine provides an inclined table which has mounted thereon a series of verticallydisposed magazines for containing stacks of lifts, and means for simultaneously ejecting the lowermost lift from each of the magazines. Located adjacent to the place of deposit of lifts ejected from said magazines is a pasting device, and beyond said pasting device, at the front of the machine, is a rocking carrier having heel-formers mounted thereon. On either side of the machine is a holder of indeterminate length for receiving the heel-blanks. After the pasted lifts are assembled in one of the heel-formers to form a heel-blank, the carrier is given a quarter turn to bring such heel-former into position opposite one of the heel-blank holders, and by operating the machine the heel-blank is forced from the heel-former into said holder. Preferably, two heel-formers are employed, so that as each heel-former is in position to have the lifts assembled therein the other is opposite one or the other of said holders. The heel-blank holders are of such length and size that as successive heelblanks are forced therein, the column of heel-blanks will be placed under pressure and will be maintained under pressure by frictional contact of the lifts, or of the largest lift, of each heel-blank vith the walls of the holder, and after the holder is full, as each fresh heel-blank is inserted a complete heel-blank, with the paste between the lifts thereof fully set, will be discharged from the rear end of the holder.

The lift-holding and delivering means and the pasting device illustrated in connection with the present machine, respectively form the subject-matter of separate applications for patent filed of even date herewith by John Mitchell, one pf the present applicants, serially numbered, respectively, 86,662 and 86,663, and filed March 25th, 1916.

The present invention is concerned more particularly with the lift-receiving and heelblank delivering mechanism. The main object of the invention is to provide a carrier having a heel-former mounted thereon which latter normally occupies a position opposite and in line with a pasting device, and which is movable to carry the heelformer with the heel-blank built up therein opposite a holder of indeterminate length and to provide mechanism for ejecting the heel-blank from the heel-former into said holder. A further object, in carrying out such main object of the invention, is to provide, in combination with a pasting device and two heel-blank holders, a rocking carrier having two heelformers mounted thereon in separated relation, the parts being so positioned relative to each other that as the carrier is rocked to bring one heel-former opposite the pasting device the other heel-former will be opposite one or the other of said holders; a further object of the invention relates to the provision of automatic means for preventing the heel-blank from sticking to or being retained in the heel-former as the latter is moved away from the mouth of the heel-blank holder after pressure has been applied to discharge the heel blank from the heel-former; and still further objects of the invention relate to details of construction and to combinations and arrangements of parts whereby the above stated objects of the invention are attained.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a view in side elevation of a heel-building machine constructed according to our invention;

Fig. 2 is a vertical transverse sectional view of the same;

Fig. 3 is a fragmentary plan view on an enlarged scale and viewed in the direction ofthe arrow 3 of Fig. 1; and

Fig. 4k is a view in-front elevation, also on an enlarged scale, and viewed in the direction of the arrow 4 of Fig. 1.

Referring now to the drawings, the frame of the machine is composed essentially of two side frame-members 1 and 2, which are connected toward their upper ends at front and rear by cross-beams 3. The framemembers 1, 2, are preferably mounted on bolsters 1, and their upper end portions 5 are inclined forward, or toward the operator. Each of the frame-members is provided in its upper end with a rectangular 1 I the rear end of which is closed by the forward edge of the cross-beam 7. Each of the frames 1 and 2 is provided in its top and forward side with a rectangular recess 10 which is adapted to receive a cross-beam 11 extending across the front of the machine, as shown more clearly in Figs. 3 and 4, and which is centrally recessed in its upper edge portion, as indicated at 12, to provide a continuation of the recess 9. To the rearof the cross-beam 7 there is mounted on the top of the side frame-members a table-section 13, said table-section, with the cross-beam 7 table-sections 8 and crossbeam 11 forming a top, or table, the upper surfaces of these parts being flush with each other, and the table as a whole being inclined downward, or toward the operator. Secured near opposite ends, respectively, of the cross-beam 7 are two standards 14 and 15, between which extend two rods 16 and 17, located, respectively, at the top and center of said standards, and having their opposite ends secured therein. The numerals 18 indicate a series of magazines, each of which, as shown by Fig. 3, is L-shaped in cross section, and affords a front wall Y19 and a side wall 20. Mounted on the front wall 19 of each magazine is a bracket-mem ber 21. Each of these bracket-members is privided toward each of its opposite ends with a slot 22 through which extends a screw-threaded bolt 23 passing through the front wall 19 ofthe magazine. A bindingnut 24 is mounted on the screw-threaded end of each of said bolts. Each of the brackets 21 is provided toward its upper end with a recessed seat 25, which is adapted to receive the rod 16. The numeral 26 indicates a clamping-plate, which is loosely mounted on a set-screw 27 having screwthreaded engagement with the bracket 21 about centrally thereof. Said clamping plate has off-set ends28 which are adapted to engage the respective rods 16 and 17 and, when the set-screw 27 is turned home,

I to draw the seats 25'of'thebrackets 18 into engagement with-the rod 16 and the lower portions 29. of said brackets into engagement with the rod 17, whereby all of the magazines are supported on the rod 16 and are held in firm, fixedpositionbyengagement of the brackets 21 with said rod and toward the operator, as shown in the'drawlllgS.

The side walls 20 of the respective magazines are parallel to each other, and, as clearly shown by Fig. 3, the several stacks of lifts 31 are retained between the side walls of adjacent magazines with their rounded ends resting againstthe front wall 19 of each magazine. In order to accommodate lifts of varying sizes provision is made for a lateral adjustment of the magazines 18, and this is accomplished by simply loosening the binding-screws 27 and sliding the magazines 18 over the rods 16 and 17 to the desired position, when the bindingscrews 27 are again turned to clamp the magazines in the adjusted positions. By inclining the magazines, as described, it is possible to retain a stack of lifts in each magazine without the. necessity of using a back wall. The advantage of this construction is fully set forth in the companion application of John E. Mitchell above referred to, and need not be recited more in detail. Slidably mounted on the tablesection 13 at the rear of the machine is an ejectorplate 32 which is of a width to extend across all of the magazines and of a thickness to work in the space or throat 30 provided between the lower ends of the magazines and the table of the machine. The ends of the ejector-plate 32 are extended'beyond the sides of the table-section 13 and are apertured to receive the upper ends of throwlevers 33, the lower ends of which are sccured in crank-arms 3 1 having hubs 35 loosely mounted on opposite ends of a shaft forward beyond'the machine so that its free end'is within easy reach of. the foot of the operator. The foot-lever 38 is normally drawn upward by means of a coil spring 39, one end of which is secured to the footle'ver and the other end to a rod40 extending between the frame-members 1 and, 2 and of the magazines and moving them out upon the top or table of the machine within easy reach of the operator. To build the heel blanks the lifts first have paste applied thereto and are then assembled successively in the heel-forming devices as hereinafter described. The pasting device comprises a receptacle 41 removably mounted at one end on a support 42 secured to the under side of the cross-beam 11 and at its other end on the rear cross-beam 8 extending between the side frames. Mounted in bearings in the side frames of the machine is a shaft 43, one end of which is provided with a pulley (not shown) by means of which it may be rotated. Secured on this shaft is a pasting roller 45 which is provided with annular circumferential recesses 46 through which extend two parallel bars 47 which are secured at their inner ends to the crossbeam 7 and at their forward ends are se cured to opposite sides of a lug 48 extending upward from a plate 49 secured on the bottom of the recess 12, as shown more clearly in Fig. 3. The roller 45 is constantly revolved by the shaft 43 and takes up the paste supplied to the receptacle 41. In practice the upper edges of the bars 47 are substantially flush with the periphery of the roller 45 and with the upper surface of the top of the machine. The forward ends of these bars extend above the lug 48 to which they are secured, and terminate flush with the outer edge of the crossbeam 11. As the paste used in the receptacle 4l is relatively thick the layer of paste adhering to the roller will project slightly above the upper edges of the bars 47 and when one of the lifts 31 is moved by the operator over the bars 47 its under side will be thoroughly and evenly supplied with paste by the roller 45.

In order to prevent the lowermost lifts from being carried backward and out of the magazines in the return movement of the ejector-plate 32, a bar 50 is provided having its opposite ends 51 bent at right angles and provided each with a slot 52 by means of which the ends 51 are adjustably secured to the respective standards 14 and 15, by

the use of setscrews 53. The bar 50 is located at the rear of the magazines l8 and extends across the same, as shown in Fig. 3, in close proximity to the rear sides thereof,

preferably being angularly disposed or inclined relative to the rear side of the magazines, as shown by Fig. 2, so as to have its point of closest approach to the magazine opposite the throat 30, and thereby avoid the possibility of offering an obstruction to the downward movement of the lifts in the on backward with it, said lifts would engage the lower edge of the bar 50 and be prevented from such movement. By loosening the set-screws 53 the bar 50 may be ad justed toward or from the magazines according as the sizes of lifts used are varied. Each end of the bar may be independently adjusted to give the bar an inclined relation to the magazines where a number of lifts are used which vary in size from a relatively large lift to a very small lift. We have illustrated only five magazines accommodating four stacks of lifts. It will. be apparent, however, that a greater or less number of magazines may be used according to the height of the heel-blanks 'to be built. The numerals 54 (Fig. 4) indicate brackets, which are bolted, respectively, to the front and rear of each of the side frames 1, 2, as indicated at Thebrackets on each side of the machine are in line with each other, but owing to the inclination of the upper portion of the side members the rear brackets 54 are at a greater distance from the base of the machine than the front brackets 54. Each of the brackets is provided at its lower end with an upstanding projection 56 and extending between and secured at their opposite ends to opposite sides of the projections, as by means of bolts 57, are two parallel rails 58. At its upper end each of the brackets 54 has an arm 59 extending outward at right angles to the frame and provided with a bearing 60. The numeral 61 indicates a relatively long, transversely-curved plate, which has secured on its upper side, at its front end, and at some distance removed from its rear end, respectively, two pins 62 which slidably engage in the bearings 60 of the front and rear brackets. at each side of the machine. It will be understood that the construction of the brackets and the parts supported thereby is the same at each side of the machine, and the constructions provide two holders consisting of the rails 58 and the curved top plate 61 which are adapted to receive between them heel-blanks 63, as shown more clearly in Fig. 4. The rails 58 project beyond the end of the plate 61 for a purpose presently set forth. The heelblanks are inserted in the holder with their flat edge or breasts resting on the rails 58 so that the curved plate 61 may engage their rounded sides. The plate 61 rests upon the heel-blanks and exerts a greater or less pres sure thereon according to the weight of the said top plate. The pressure exerted on the heel-blanks produces the necessary frictional resistance to the movement of the heelblanks through the holders, whereby the pressure applied in moving the column of heel-blanks through the holder will result in placing all of the heel-blanks under compression, and they will be held under such compression until discharged from the holders. Rotatably and slidably mounted in suitable bearings 64 provided centrally of the two cross-beams 3 is a shaft 65, which, as

shown particularly by Fig. 2, projects a considerable distance beyond the front end of the machine. The numeral 66 indicates a yoke-member which spans the forward cross-beam 3 and is provided at its opposite ends with-bearings 67 and 68, respecon a shaft 7 2 extending across the machine and mounted at its ends in bearings 73 provided in the side frame-members 1 and 2. One arm of this bell-crank lever is in the form of a yoke 71 which embraces the bearing 67 and the respective members of which are slotted at their outer ends, as indicatedat 74 (Fig. 1) to receive the trunnions70. The other arm of the bell-crank lever 71 is pivotally connected at 75 (Fig. 2) to the upper end of a connecting rod 76,

, the. lower end of which is pivotally con nected at 77 to the foot-lever 38 interme diate the ends of the latter. Toward the outer ends of the shaft 72 are fixedly secured crank-arms 78 (Figs. 1 and 2) the outer ends of which are pivotally connected at 79 to the ends of'connecting rods 80, the opposite ends of which are pivotally connected at 81 to the respective throw-levers 33. The members of the yoke 71 of the bell-crank lever 71 are provided with setscrews 82 respectively, which are turned into engagement with the opposite sides of the yoke-member '66 and thereby prevent said yoke-member from turning. The numeral 83 (Fig. 4) indicates a rocking carrierwhich is in the form of a bell-crank lever having arms 84 and 85 extending at right angles to each other and connected to a hub 86 (Figs. 1 and 2). This hub is mounted on the outer end of the shaft 65 and fixedly secured thereon by means of a set-screw 87. The hub 86 is located adjacent -to the bearing 68 of the yoke-member 66 (see Fig. 2), and acts as a thrust-bearingv for the yoke-member 66 in moving the carrier 83 and shaft 65 outward in the operation of the machine, as later explained.

The outer end of each of the arms 84 and 85 is provided with a cylindrical bearing 88. The numeral 89 indicates the backplate of a heel-former, one ofwhich is mounted on each of the arms'84, 85, by means of a wrist-pin 90 secured on the front faceofsaid back-plate and rotatably mounted in the bearing 88, and secured therein by means of a collar 91 mounted on the end of said wrist-pin and fastened thereonby means of a set-screw 92. Secured to'and projecting inward from each back-plate 89 are two bars 93 which form the bottom of the heel-former and when the latter is 0ppositethe pasting device, as shown by Fig. 3, are in line with and substantially form continuations of the rails 47, their upper edges being flush with the upper edges of said rails,-the latter feature being more clearly illustrated in Fig. 1. Mounted near opposite sides of each of the back-plates 89 are guide-members 94, which are adjustable in slots 95 formed in said back-plate (Fig. 4) the guide-members having screwthreaded ends extending through said slots and being provided with jam-nuts 96. By loosening these jam-nuts the guide-menu bers 94 canbe moved closer together or farther apart according to the width of the lifts being employed for building the heelblank. The guide-members 94 have their inner edges outwardly inclined, as shown by Fig. 3, and serve as the sides of the heelformer, and insure the correct positioning of the lifts as they are forced into the heelformer, as will be clearly understood by those skilled in the art. Each of the backplates 89 has at its outer end an integral depending arm 97 towhich is pivotally secured at 98 the upper end of'a connecting rod 99, the lower ends of which arms 99 are pivotally secured at 100 to the front of the yoke-member 66 at opposite sides thereof. Each of the wrist-pins 90 is provided with a longitudinal aperture which also extends through the back-plate 89, and in this aperture is slidably mounted an ejectingpin 101 (see Figs. 1 and 2), the outer end of each of'which pins is pivotally connected at 102 to the outer end of a floating lever 103. Each of the arms 84, 85, is provided near the hub 86 with a cylindrical enlargement 104 which is apertured to slidably receive a contact-pin 105, the outer end of which is pivotally connected at 106 to the lower end of the floating lever 103.- Each of the floating levers 103 is provided on its inner side with a lug 107 for engagement with the outer side of the respective arms 84 and 85, and above this lug it is off-set or curved outwardly, as indicated at 108, to extend beyond the outer end of the wristpin 90. Below the lug 107 each of the floatof the heel-former, will lie directly oppo-' site the outer ends of the rails 47 of the pasting device. This movement of the bellcrank lever 71 also rocks the shaft 7 2 which, through the crank-arms 78 and connectingrods 80, serves to throw the upper ends of the levers 33 inward moving the ejector plate 32 under the magazines 18 and forcing the lowermost lift in each of said magazines through the throat 30 to a position on the top of the cross-beam 7 which, as stated, forms a portion of the top of the machine.

The operator first places the bottom or smallest lift to be used, which does not require to be pasted, in the heel-former and then, taking the lifts deposited on the table in the order in which they are to be assembled, moves them rapidly over the rails 47 which constitute a slideway, in which operation the roller 45, which travels in the direction of movement of the lifts, that is, toward the operator, will apply paste to the under side of each lift as it is moved over the slideway. After passing over the pasting roller the lift is turned up on its flat edge or breast, as indicated by the dotted lines in Fig. 1, and pressed into the heel-former between the guide-members 94, this operation being continued until the number of lifts necessary to complete the heel-blank has been deposited in the heelformer. During this operation the footlever 38 will be held depressed. Upon completion of the heel-blank the foot-lever 38 is released and is drawn upward by the spring 39. In this movement the upper ends of the levers 33 will be drawn outward to I carry the ejector-plate 32 beyond the rear sides of the magazines, and the bell-crank lever 71 will be actuated to throw the yokemember 66 toward the operator, in which movement its bearing 68 will engage the hub 86 of the rocking carrier 83 and move the latter, with the shaft 65, outward to the position shown in Fig. 2. Assuming the arms 84 and 85 to be in the position shown in Fig. 1, the operator next places his hand upon the arm 84 and rocks the carrier 83 to the left to bring its heel-former with the completed heel-blank therein into a position remote from the support and opposite the mouth of the holder at the left of the machine, as shown in Fig. 4, and at the same time move the heelvformer on the arm 85 opposite the pasting device. It is.

former.

necessary in this movement of the rocking carrier 83 that the heel-lolank 63 be maintained in the position shown in the drawings, that is to say, with its rounded side upward, so that it may be inserted in the holder with its flat or breast side resting on the rails 58; and this is accomplished hrough the medium of the connecting-rods 99 which operate to hold the back-plate in a horizontal position, the wrist-pin 90 of each heelformer in the movement described turning in the respective bearings 88. The

' heel-former with the heel-blank therein hav-- ing been brought opposite to the holder as described, the foot-lever 38 is again depressed, thereby operating the ejector-plate 32 and the rocking carrier 83 in the manner previously described, and in such movement the heel-blank is forced into the holder, that is to say, between the plate 61 and the rails 58 and at the same time the end of the contact-pin 105 engages the face of the forward cross-beam 3 and moves the inner end of the floating lever 103 outward against the resistance of the spring 109, which latter forms a movable pivot causing the inner end of the pin 101 to come in contact with the heel-blank. When the foot-lever 38 is again released the rocking-lever 83 is moved outward, as previously described, carrying the heel-former from about the lift which has been deposited in the holder. As the rocking carrier moves outward the power of the spring 109 is sufficient to force the pin 101 inward and prevent the heel-blank from adhering to or remaining wedged in the heel- The position of the floating lever 103 when the rocking carrier 83 is in its inward position is shown in Fig. 3, and its position when the rocking carrier has been moved outward, is shown in Figs. 1 and 2. In these latter figures, however, the floating lever is shown in connection with the heel-former that is opposite the pasting device, and not that which is opposite a heel-blank holder. The position of the parts is exactly the same, however, except that in the latter case there would be no heelblank in the holder. As soon as the rocking carrier has moved far enough to withdraw the end of the pin 105 from contact with the machine, the spring 109 draws the floating lever inward, and as the lug 107 comes in contact with the arm 84 or 85, it forms a fulcrum which causes the inner end to be moved into contact with the arm, and the pin 101 to be moved outward to carry its inner end beyond the forward face of the back-plate 89. It will be understood that, in operation, the rocking carrier 83 is turned first to one side and then to the other so that as one of the heel-formers is opposite one or the other of the holders, the other heel-former is opposite the pasting device. The motion of the rocking carrier 83 in either direction is arrested by the bottom of the back-plate 89 coming in contact with and resting upon the rails 58, more clearly shown to the right in Fig. 4:, and in this position the bottom members 93 of the heel-former lie between the rails'58 with their iippersurfa'cessfiush with the upper surfaces of said rails, as shown by the dotted lines in said Fig. 4.

In a heel-building machine, in combination with a pasting device, a holder for receiving heel-blanks, a carrier having a heel-former mounted thereon and movable in either direction to alternately position the heel-former opposite said pasting device and said holder,-means for reciprocating the carrier to force a heel-blank from its heel-former into said holder, a push pin mounted in said heel-former, a floating lever connected at one end to said push pin, a spring connected to said floating lever intermediate its ends, and a contact member carried by said lever and adapted when the can rier is moved toward the holder to engage a fixed part of the machine and place said spring under compression, whereby as the carrier is moved away from the holder said spring will draW the push pin inward to engage'a heel-blank and prevent its Withdrawal With the heel-former.

20. In a heel-building machine, in combination With a support for lifts, a holder for receiving heel-blanks and maintaining them in column formation, and a carrier having a heel-former mounted thereon and adapted to be moved successively to positions opposite said support and said holder.

21; In a heel-building machine, in combination with a pasting device, a holder for receiving heel-blanks and maintaining them having a heel-former mounted thereon and adapted to be moved alternately into a posireceiving end of said holder and remote from said support, andmeans for dlscha'rging a heel-blank under pressure from the heel-former directly into said' holder.

28. In a heel-building machine, in combination With a support for lifts, an elon gated holder open at both ends for receiving heel-blanks, and a carrier having a heelformer mounted thereon and adapted to be moved alternately into a position opposite and adjacent said support, and into a position adjacent to and opposite an open end of said holder andiremote from said support.

In testimony whereof, We have hereunto set our hands.
